Title: Formation of Metal Patterns
IPC: C08F283/01
Filed: 1967-05-11
Abstract: A metal pattern on a support is formed by imagewise exposing a material having a flexible support bearing a light-sensitive resin layer whose softening point is at least 30 C. and is raised by light exposure, and pressing the layer in contact with a flexible electrically conducting metal layer on an electrically insulating support while heating to a temp. greater than the softening point of the resin before exposure but less than the softening point after exposure, thereby transferring a stratum of resin the unexposed areas to the metal layer and thereafter etching all the metal from the unprotected areas. The resin preferably has a softening point of 60-150 C. after exposure and may be a polyester of one or more dihydric alcohols and one or more dicarboxylic acids, at least one dicarboxylic acid residue having the group -CH = CH-CO-. Exemplified resins are 1, 4-butane diol polycinnamylidene malonate, a pentamethylene terephthalate/pentamethylene benzene diacrylate copolymer, and a pentamethylene azelate/pentamethylene benzene diacrylate copolymer. The resins may contain sensitizers, plasticizers and colorants.

Patent ES-364403-A1 (ES)
Title: Electrical power supply system for automotive vehicles and particularly polyphase bridge-type rectifier therefor
IPC: H02J7/14
Filed: 1969-03-05
Abstract: A 3-phase bridge rectifier 8 to 13 (Fig. 1) coupling a vehicle engine driven alternator 1 to sundry load on the vehicle, is provided with Zener diodes 12, 13 in one arm to limit the voltage between lines 6, 7 to about 38 Volts. It is stated that excess voltage between these lines can occur when starter motor 20 is operated also when a load 18 is suddenly switched off causing the alternator voltage to rise e.g. to 250 V. if the battery 16 is disconnected. A regulator 21 is set to maintain the alternator voltage to 14 Volts but its response to sudden excess voltage is not sufficiently rapid to prevent damage to itself and other components. Additionally the rectifiers 10, 11 may be Zener diodes (Figs. 5a, 5b, not shown). Rectifiers 8, 10, 12 are mounted on one cooling plate and 9, 11, 13 on another, the plates also being conductors, Fig. 4 (not shown). Regulator.-The regulator 21 is connected to the output of a second bridge comprising rectifiers 23 and the rectifiers 9, 11, 13 and controls the energization of the alternator field winding 5, by means of transistor switches 33, 34, which conduct alternately at a switching cycle frequency of 10-100 c.p.s. When the alternator voltage is low the potential at point 27 in a voltage divider is low whereby a Zener diode 32 is blocked. Hence transistor 33 has no base current and is non-conductive. Its collector is therefore positive relative to lead 7 so that transistor 34 conducts and current flows in winding 5 increasing the alternator voltage. As the alternator voltage increases the potential at point 27 increases until eventually Zener diode 32 breaks down causing transistor 33 to conduct which renders transistor 34 non-conductive stopping the field current supply. Current will continue to flow in winding 5 briefly via diode 38. At least one of the dioes 23 may also be of Zener type (Fig.6, not shown).
Patent ES-366445-A1 (ES)
Title: Improvements in or relating to non-woven fabrics
IPC: D04H3/009
Filed: 1969-04-25
Abstract: A fabric characterised by having a fabric surface-fabric surface dynamic coefficient of friction not greater than 0.4 and an abrasion resistance of at least 300 cycles is made by air laying a web of randomly arranged continuous filaments, at least some of which are potentially-adhesive bicomponent filaments able to increase in length by at least 3%. The web is exposed to moisture such as steam at atmospheric pressure to effect the increase in length of the filaments while preventing the web changing in length or width. The filaments then lie at an angle of 45-90 to the mid-plane of the web. The web is heated to render the filaments adhesive so as to produce between 0.05 and 0.2 bonds per filament at the plane of greatest bonding. The preferred filaments are of polyhexamethylene adipamide sheathed with a copolymer of hexamethylene adipamide and epsilon caprolactam.

Filed: 1978-01-03
Abstract: A reversible plough is attached to the three point hitch of a tractor by a bracket (2) with a support block (8) with two spaced apart collars forming bearings for the reversing shaft.

Patent ES-8101451-A1 (ES)
Title: Rotary cutterblock and method for its manufacture.
IPC: B27G13/00
Filed: 1979-05-28
Abstract: A rotary cutterblock for woodworking machinery has a body made up of a row of discs (10) of different diameters. The disc diameters are chosen to approximate, as far as possible, the profile of a timber moulding to be formed, and discs can be selected from a stock of standard sizes. The use of spacers (22) between adjacent discs enables the mass to be kept to a minimum. The cutterblock is quiet in use, especially when blades clamped in successive discs are staggered around the circumference of the cutterblock. A preferred method of manufacture of such a cutterblock having staggered blades comprisises initially mounting the discs (10) on a mounting shaft with the blades (14) in axial-alignment for grinding purposes, and then removing the discs (10) from the mounting shaft and reassembling them in the same sequence but angularly offset one from another.
